Description

Verfahren zur Überführung von Salzen, insbesondere Düngemitteln, in kugelige Gebilde oder Körper ähnlicher Form durch Eintropfenlassen des geschmolzenen Materials in eine bewegte Flüssigkeit Verfahren zur Ubertührung von Salzen. insbesondere Düngemitteln, in kleine kugelige Gebilde usw. sind in der Literatur bereits beschrieben. Die Verfahren bestehen im wesentlichen darin, daß man das WIaterial in geschmolzenem Zustande in gekühlte. bezeigte Flüssigkeiten, in denen es unlöslich ist, eintropfen läßt. Hierbei ist es erforderlich, daß den einzelnen Tropfen der Schmelze auf ihrem ziege durch die Kühlflüssigkeit genügend Wärme entzogen wird, damit sie beim Auftreffen auf dem Boden des Kühlgefäßes schon fest genug sind, um nicht zusammenzukleben und durch die Fördereinrichtung zerquetscht zu werden. Dies wurde bisher z. 13. dadurch erreicht, daß man ein sehr hohes Kühlgefäß verwendete und eine Flüssigkeit von möglichst hohem spezifischem Gewicht und tiefer Temperatur wählte.Process for the transfer of salts, in particular fertilizers, into spherical structures or bodies of a similar shape by dropping the molten material into it Material in a moving liquid Process for the transfer of salts. in particular Fertilizers, in small spherical structures, etc. have already been described in the literature. The method consists essentially in that one of the WImaterial in molten Condition in chilled. Drip shown liquids in which it is insoluble leaves. Here it is necessary that the individual drops of the melt on their The coolant extracts enough heat from the goat to ensure that it hits the ground are already firm enough on the bottom of the cooling vessel not to stick together and to be crushed by the conveyor. This has been z. 13. by it achieved that you used a very tall cooling vessel and a liquid of as possible high specific gravity and low temperature.

Es wurde nun gefunden, daß man in bedeutend einfacherer Weise zu dem gleichen Ergebnis gelangt, wenn man die Geschwindigkeit der in der Kühlflüssigkeit fallenden Tropfen durch Bewegung der Flüssigkeit im Kreislauf um die vertikale Achse des die Flüssigkeit enthaltenden Gefäßes verringert. It has now been found that one can in a much simpler way the same result is obtained if one considers the speed of the in the coolant falling drops by moving the liquid in a circuit around the vertical axis of the vessel containing the liquid is reduced.

Die Bewegung der Kühlflüssigkeit kann beispielsweise durch einen Rührer mit vertilialer Welle und einem oder mehreren Flügeln hervorgebracht werden. Sie kann aber auch dadurch erzeugt werden, daß man die Kühlflüssigkeit z. B. im Zentrum des Bodens des Granuliergefäßes absaugt und sie durch eine Pumpe tangential in das Gefäß mit entsprechend großer Geschwindigkeit wieder einführt. Bei entsprechender Einstellung der Strömungsgeschwindigkeit der Kühlflüssigkeit werden auf diese Weise die einzelnen Schmelztropfen lange Zeit in der Flüssigkeit in der Schwebe gehalten, so daß sie ihre Wärme vollständig abgeben und erstarren können. ohne daß die Kühlflüssigkeit weitgehend abgekiihlt werden muß.The movement of the cooling liquid can be done, for example, by a stirrer be produced with a vertical shaft and one or more wings. she but can also be generated by the fact that the cooling liquid z. B. in the center suction from the bottom of the granulating vessel and tangentially into the Reinsert the vessel at a correspondingly high speed. With the appropriate Adjusting the flow rate of the cooling liquid will be done in this way the individual melt droplets kept in suspension in the liquid for a long time, so that they can give off their heat completely and freeze. without the coolant must be largely cooled.

Beispiel Kalksalpeterschmelze mit etwa 12,5 01o Wasser in Tetrachlorkuhlenstoff eintropfen lassen. Die Kühlflüssigkeit befindet sich in einem runden Gefäß und wird darin zur Bewegung im Kreislauf um die vertikale Achse des Gefäßes gebracht. Schon bei geringer Höhe der Kühlflüssigkeit kommen die Tropfen infolge des durch die Bewegung der Flüssigkeit verursachten langen Spiralweges genügend fest am Boden des Gefäßes an. so daß sie nicht zusammenkleben und auch nicht zerquetscht werden. Example Lime saltpeter melt with about 12.5 ° C water in tetrachloride tub material let drip in. The coolant is in a round container and is therein brought to movement in the circuit around the vertical axis of the vessel. Nice If the level of the cooling liquid is low, the drops come as a result of the movement the long spiral path caused by the liquid sufficiently firm on Bottom of the vessel. so that they do not stick together and are not crushed either will.
